Which statement describes the Richter scale? It cannot account for fault movement during an earthquake. It measures large earthquakes far from the seismograph. It estimates the total energy released from an earthquake. It increases in magnitude as amount of damage increases. on edg
Answers
Answer:
It estimates the total energy released from an earthquake
Explanation:
The Richter scale was developed in the early half of the 1930s but seismologists from the US, namely, Charles Richter and Beno Gutenburg. The scale is essentially a logarithmic scale that calculates/estimates the largest peak of energy released during an earthquake. This peak is than proscribed a number from 1 to 10 on the scale with each number denoting the strength of an earthquake as 10 times the strength of the number below it. It accounts for movenent along the fault length (since that is essentially an earthquake) and the the Richter magnitude is calculated using a seismograph. Therefore, an earthquake that cannot be located on a seismograph cannot be incorporated on the Richter scale. There is no such directly proportionality between magnitude and amount of damage since a small earthquake in a densely populated area can cause way more damage than a strong earthquake is a desserted region. Furthermore, Richter scale determines the magnitude which impacts damage. Its not the other way round
Answer: a

Explanation:
b) its the longest day of the year
A. You are travelling on a summer solstice if you have experienced the longer day in the Northern hemisphere and about to experience the shortest day on the southern hemisphere.
First of the rotation of the North and South hemisphere is what gives us seasons. Summer solstice is the year's longest day and its shortest night.
B. To explain this phenomenon, I would tell this person that the sun is at it farthest position from the sun in the North and it goes on the farthest path. This far movement is the reason for the long day.

The passage states that "rising ocean temperatures also affect the ecosystems in the coral reef, throwing off the delicate balance that allows so many species to coexist." Explain how rising ocean temperatures, pollution, or human interference could throw the ecosystems of the Great Barrier Reef off balance. Support your answer with evidence from the passage
Answers
Answer:
Rising ocean temperatures will influence reef species to move to another area that has cooler areas.
Pollution will create dead zones where there are little to no wildlife. Material pollution like plastic will also kill marine life.
Human interference can affect the ecosystems by polluting, overfishing, and destroying coral.
Explanation:
Some marine life are not suitable to warm temperatures, and this will cause them to move to cooler ones, disrupting the normal balance the ecosystem once had.
Pollution from fertilizer runoff and others can deplete the oxygen in the water, and animals like turtles believe plastic is food and will kill them by destroying internal organs and blocking intestines.
Humans pollute and overfish, and this throws the ecosystems off balance because it will create dead zones and will significantly decrease the amount of wildlife there. Humans also destroy coral, which will make reefs die and destroy habitats for wildlife.
The rising temperatures, pollution, and human interferences affect the ecosystem.
What does the passage state?As per the passage, the rising ocean temperatures are affecting the ecosystem and the coral reefs are getting depleted. The throwing of the wastes and other dumps into the oceans at large affects their survival and also impacts the species.
As is a known fact that global warming and climate change affect the lives and habitats of the living organism they also affect the behavior of the species.
Thus the passage tells about the growing temperature and destruction of different ecosystems.

What is the future of the Mogollon Rim (edge of the plateau around Promontory Butte)? (Consider the gradients of the streams above and below the Rim, and their contrasting erosion potentials.) (6 points)\
Answers
Answer:
The Mogollon Rim will be eroded back to the northeast due to Christopher Creek.
Explanation:
This question refers to the Promontory Butte of Arizona map.
The Mogollon Rim is the edge of the plateau around Promontory Butte, the main cliff of which is an erosional escarpment.
The Mogollon Rim is a steeply sloping cliff that rises from 1,000 to 7,500 feet at its upper edge.
Groundwater flow in the area is generally northeast to southwest. The Mogollon Rim tends to have greater rainfall and snow which provides greater volumes of recharge to the groundwater systems both north and south of the Rim.

The location of population centers of South America can be determined using the map. Thus, the correct answer is option C.
What is a population center ?In demography, the centre of population of an area refers to the geographic location that best captures the region's population centre. Such a "central point" might be defined in various ways, each of which leads to a distinct place.
Brazil accounts for about half of South America's population with a population of over 200 million. After Brazil, there are 50 million people in Columbia, 44 million in Argentina, 31 million each in Peru and Venezuela, and 50 million in Columbia.
The largest city in South America is Sao Paulo, Brazil, which has 12 million residents. Lima, Peru, has 8.9 million, and Bogotá, Columbia, has 7.9 million.
Therefore, the geographic information about South America can be determined using the map is the location of population centers.

Discuss any five effective mechanism you will employ in ensuring sustainability sustainability of soil fertility in an area
Answers
Answer:
Sustainability of soil fertility includes maintaining the nutrient's concentration in soil. Some of the effective mechanism to ensure sustainability of soil fertility in an area are as following:
Maintaining the process of crop rotation to ensure the fertility of the soil.Growing legumes for nitrogen fixation of soil rather than chemicals.Performing leaching in the crop rooting zone that will maintain flow of water and nutrients and minimize nutrient loss.Use of nitrogen-15 isotopic technique that determines the amount of nitrogen fixed in the soil and provides data on how much more nitrogen is required.The carbon-13 isotope technique is used to measure the contribution of different types of crops in the fertility of soil.Hence, by taking the above measures soil sustainability can be maintained.
